Hello!
Any help would be very much appreciated -
I have a file with exact duplicate records and I just want to skip then during a load.
(Using 'distinct' in my extract makes the query perform like a dog. I don't want to load all the duplicates then weed them out because it's 3GB of data compared to 300MB).
Many thanks,
Scott

I had the same problem. To fix it intermediate file "list.txt" was used in control. Option "-u" for sort does the job:
sort -u list_orig.txt > list.txt
sqlldr db/pswrd@instance control=control.ctl
